Description

I am trying to run ESP32-4848S040 display with the latest 3.0.0-rc3, but I keep getting the same error.
I am using Arduino_GFX_Library.

If I use the latest release (2.0.16), the issue is gone, but I don't like changing between versions all the time.

Other Steps to Reproduce

No response

I have checked existing issues, online documentation and the Troubleshooting Guide

The used Arduino_GFX_Library is not espressif32 Arduino core 3.0.0 compatible.
You should ask the maintainer of the Arduino_GFX_Library to update to make it work with core 3.0.0

[jesetek]

He told me that 3.0.0 version does not yet support RGBPanel and to wait for 3.0.0 version to update and start supporting it

[Jason2866]

Why dont you write exactly this in the headline? Feature Request: Support for RGB LC Displays and the link where you got the statement.

[jesetek]

Because I wanted to solve this myself, but I need some advice in which files to look since I couldn't find anything

[TigoTas]

So...

No workarounds other than waiting for either Espressif or @moononournation?

[Jason2866]

@TigoTas espressif does not have a task here. You can use the mentioned Display with Arduino. Just not with the mentioned 3rd party library.

As mentioned above, here is not much we can do, closing the ticket. Thanks for understanding.
